It serves as a guiding document that aligns stakeholders on priorities, timelines, and expected outcomes. By detailing how technology will evolve, it helps teams anticipate and respond to market trends, customer needs, and emerging innovations. A well-defined roadmap fosters collaboration and ensures resources are allocated effectively to achieve objectives.
